DEVICE FOR DRYING, STEAMING, AND CONDITIONING TUBU 'LAR FABRICS.

Application filed December 8, 1927. Serial No. 238,604.

My invention relates to a means for raising the moisture content of fabrics, as woolens, for example, or in the case of fabrics having excess moisture to remove such excess moisture.

It is necessary under some conditions when fabrics are too dry and lack the proper feel, as it is termed, to put the fabric througl-i a process called conditioning,

which process increases the amount .of moisture in the fabric.

The general object of my invention is to provide a device over which tubular fabrics, or fabrics sewn into tubular form, may be drawn, and which device may be used, first, for drying the fabric to remove the excess moisture, and then steaming or Wetting the fabric to give the desired finish. .Or, ,the device may be used, first, for steaming the fabric and then drying to give the proper finish.

The nature of my invention and its ,distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is an elevation of the .device embodying my invention;

Figure 2 is a vertical section of the device, the air and steam supply means being omitted;

Figure 3 is a horizontal section taken on the line of Figure 2.

The device includes a duplex coil, .the con volutions of one coil alternating with the .convolutions of the other ,coil, the convolutions of one coil being perforated for approximately that half of the coil nearest the steam or air inlet and imperforate for the remainder of the convolutions, while the convolutions ofthe other coil are imperforate for approximately that half of the coil nearest the steam and air inlet end and perforated for theremainder of the convolutions of the coil.

In ,the illustrated example the numeral 10 indicates the convolutions of one coil having an inlet 11 at one end usually positioned to constitute the lower end of the device. The inlet 11 passes through a flange 12 rigid with said inlet 11 and into a supply pipe 14 tapped into a flange 13, the two fll5anges 12, 13 being secured by clamped bolts Leading into the supply pipe 14 is an inlet 16 with which is" connected a steam pipe 17 and an air pipe 18 respectiyely having valves 19 and 20 so that either air or steam may be directed to supply pipe 14 and thence into inlet 11 and convolutions 10 of the duplex coil.

Those convolutions l0 nearest the inlet 11 of the device have perforations 21, While at the opposite end of the device the convolutions 10 are imperforate. Alternating with the convolutions 10 of the duplex ,coil are convolutions 22 which are i-mperforate at 7' that end orportion of the device adjacent to the inlet pipe 23. Those convolutions 22 at that end of the device farthest from the inlet pipe 23 have perforations 24;. Thus, it is to be noted that while the convolut ons I 10 are perforated for approximately that half of the device adjacent to the inlet 11 of said convolutions 10, the convolutions 22 are imperforate at that end of the device adjacent to the inlet,23 and are formed with perforations 24 at that portion of the duplex coil remote from the inlet.

The numeral 25 indicates a supply pipe leading to inlet 23 tl-irough flanges 12, Leading into said supply pipe 25 is an inlet 26 communicating with which is a steam pipe 27 and air pipe 28 equipped respectiyely with valves 29 and .30.

The numeral 31 indicates .a steam trap, conventionally shown and of known form, communicating with supply :pipe 14;, and the numeral 32 indicates a similar trap cominunica-t-ing with supply pipe 25.

The mimeral 33 indicates a concave bot tom plate at the inlet-end of the duplex coil, and the numeral 34 indicates a domed ,plate or top of the duplex coil.

The final convolution. 10 at the outletend of the duplex'coil has a terminal shut-off valve 35. .Similanly, the final convolution of the alternating .coil 22 terminates in a shut-off valve 86.

The numeral 37 indicates a stretcher frame, the bottom 38 of which is secured in any suitable manner to the top plate ordome 34 of the device, it being understood that the said stretcher frame and its mode of fastening form no part of the present invention.

In the above describeddevice the valve 19 1110 may be closed and valve opened to admit air to inlet 16 through supply pipe ll and to convolutions 10 through inlet 11. The perforations 21 adjacent to the inlet 11 permit the escape of the air to the fabric indicated at A in Figure 1 when said fabric is drawn over the coils. Air escaping from perforations 21 will be directed against the fabric until the imperfora'te portion of the convolutions 10 remote from the inlet 11 reached, whereupon the application of the drying air to the fabric will cease.

Fabric after being dried requires to be steamed to give the necessary finish, and for this purpose the valve 30 may be closed and the valve 29 opened, whereby steam will pass through the inlet 26 and through supply pipe and inlet 23 to the imperforate portion of the coil 22 nearest the inlet Steam will not escape from the convolutions 22 until the perforated portion is reached or that portion remote from inlet 11 and l aving perforations 24 for the escape of the steam against the fabric. Steam or air escaping from the convolutions 10 or 22 is prevented from finding its way to the interior of the coils by closing the coils inside against the flow of air, for which purpose in the illustrated example a closed hollow cylinder or cylindrical box 39 is shown.

At times it is necessary to increase the moisture in the fabric and this may be done as follows: The valves 19 and 20 are both opened and at the same time ordinarily the valves 29 and 30 are closed. The combined steam and air will pass through the inlet 16, supply pipe 1a and inlet 11 to the con volutions 10, the resulting fluid mixture es caping through perforations 21 in the form of a very fine spray.

If additional moisture is required the valves 29 and 30 may be opened and operated in the same manner to obtain a flow of mixed steam and air through inlet 26, sup ply pipe 25 and inlet 23 to convolutions 22 and perforations 24:.

The degree of moisture can be regulated owing to the fact that the mixing of the air with the steam produces a condensation which will be according to the amount of air admitted to the presence of the steam.

Whenever dry steam is desired it may be produced by opening the steam valve 19 and at the same time opening the air valve 20 to admit hot air and steam to said inlet 16, which adjustment of the device will result in the steam being discharged from the device against the fabric in a dryer superheated form.

I would state furthermore that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the eXect details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.
